Application filed February 16, 1923. Serial No. 619,505.

To ail whom it may concern:

Be it known that I, AUGUST -FALSANI, a citizen of the United States, and resident of Sanford, county of York, State of Maine, have invented an Improvement in Door F asteners, of whichthe following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts in each of the several views.

This invention relates to door fasteners of a type adapted to be detachably applied to the door at the inner or room side thereof and engaged with the door jamb in a manner so as to insure the door against being opened from without, irrespective of any tampering with the ordinary locking means. A principal object of the invention is to provide a device of this character that is exceptionally strong and serviceable, while being at the same time small and compact in dimension and of few parts, so that it can be easily carried about for use as required. A further object is to provide a small and portable door fastening device that can be instantly applied to, or removed from, the door and requiring no particular skill for its secure application. In its pre ferred embodiment my improved fastening device comprises only three parts which are hinged or pivoted together for setting up into operative position, or for folding up to be put away when not in use. The foregoing and other objects and advantages of the invention will more fully appear from the following detailed description taken in connection with the accompanying drawings, and the distinctive features of novelty will be pointed out in the appended claim.

Referring to the drawings:

Fig. 1 is a plan view of a device embodying'the invention showing the same applied to a door and with portions of the door and door jamb in horizontal section;

Fig. 2 is a front elevation of the device as set up for use, i. e. as in Figure 1;

Fig. 3 is a plan or edge view of the device when folded to be put away, or in readiness to be applied to a door; and

Fig. 4 is a front or face view of the device in the position of Figure 3, and as seen looking from the left in Fig. 3;

All the parts of the device except the pivot pintles may be, and preferably are.v

pressed or struck out of stoutplate or bar metal stock such as malleable iron or steel.

A plate member 10 has one end portion thereof bent laterally at right angles as indicatedat 11, and with its extremity beveled as indicated at 11 to provide a beak with a relatively sharp edge adapted to penetrate into the wood of the door jamb J. This plate member is slitted from its other end I at each side of its transverse median line as indicated at 12, 13 provicing a central tongue 1 2 and strap portions 15,16 at each side thereof. These strap portions are bent backward against the material of the plate 10 beyond the slitted portion thereof, and the extremities of these straps are bent-over outward as indicated at 17 to provide hold: ing sockets or hinge knuckle members for a pivot pintle 18 which is secured therein. The extremities of this pintle project outward from these sockets and h ve pivotally fitted thereon, one end of a plate member 19, which is forked as indicated at 19 to receive the inner or unslitted portion of the member 10. For thus pivotally securing the member 19 the extremities of the forks thereof are preferably bent upon themselves as indicated at 19 to provide hinge knuckles adapted to turn on the pintle 18, though it is to be noted that it is immaterial whether this pintle be stationarily held in the knuckle member 17 with the knuckles 19 turning thereon, or vice versa. The other extremity of the member 19 is bent laterally at right angles as indicated at 19 to provide a ledge or abutment for a purpose now to be explained. The extremity of the tongue 14 is also bent upon itself as indicated at 14, to

provide a hinge knuckle through which is passed a pivot pintle 20, which extends outward at each side thereof. The end portions of this pintle are engaged in hinge knuckles 21 formed at one end of a flat plate member 22, one end portion of which is forked at 22 to receive the hinge knuckle '14-. of-the tongue 14. It will be observed that the unslittcd portion of the member 10 extends a substantial distance beyond the hinge provided by the pintle 18 with the penetrating beakprovided by the laterally turned beveled or sharpened portion 11 at the end thereof. In use this projecting por tion of the plate or bar 10 is applied against the door jamb J with the beak 11 in position to be pressed into the door jamb, this being done while the door D is open, and with the members 19, 22 turned outward, i. e. to approximate alinement with the bar as indicated in Figure 3, so as to permit the door to be swung to a closed position. 7

'jamb as indicated in Figure l and serves as a backing to prevent removal thereof, so long as the door is closed. Then the member 19 is swung inward to lie substantially flush with the inner side of the door and the member 22 is swung in so that its extremity engages against the ledge or abutment 19 as best shown in Figure 1. Thus the plate or bar member 19, with the member 22, as a strut or brace for the outer end thereof serves as a lock and retaineradapted to Withstand any thrust or pressure that may be exerted upon the door tending to open the same. Since any such thrust or pressure is exerted directly upon the bar 19 through the pintles 18 and 20, it results that the door is securely held closed and could only be forced open by sufficient pressure to break or mutilate the ja-mb J. It will be noted that with the parts disposed as in Figure 8, i. e. with the members 19, 252 swung outward, the device takes up comparatively little room and may be packed away in small space. Vhile I have herein shown one convenient and illustrative con struction and way of producing the two hinges, with a minimum number of parts, i. e. by forming the knuckle members 17 from straps folded back from the material of the plate 10, and producing the other knuckles by folded over extremities of the respective members, I do not desire to be limited to such construction since other expedients may be employed for the same purpose, and in this as well as other particulars desire the present embodiment to be considered as illustrative and not restrictive and refer to the appended claim rather than to the foregoing description to indicate the scope of the invention.

7 Having described my invention, what I claim as new and desire to secure by Letters Patent is:

A door fastener, comprising a bar or plate member having a penetrating beak at one end adapted to be pressed into the door jamb, a swinging strut or brace pivoted to the other end of said bar or plate, and a member pivoted to said bar or plate at a point inward a substantial distance from said strut pivot, adapted to be swung transversely of the bar or plate and formed to engage against the inner side of the door relatively close to the pivot thereof to said bar, said member equipped at its outer end with a ledge adapted to engage the extremity of said strut, the relative dimension of said members and said strut being such that with said strut in operative position engaging said ledge, it extends at a relatively wide angle with reference to said door-engaging member.

In testimony whereof, I have signed my name to this specification.
